Labconco has engineered the Gas Purifier to meet the ISO 10648-2 Class 1
atmosphere leak specification when used with Labconco controlled atmosphere
glove boxes. The information that follows details performance features so you
can get the most out of your Gas Purifier. Refer to Figure 4-1.
Gas Purifier Performance Features
1.)
Capacity to remove up to 5 liters of oxygen (13,500 ppm) and 660
grams of moisture (18 million ppm) with normal oxygen and
moisture permeation rates below 0.16 ppm/min. The adsorption
column contains 5 lbs of copper catalyst to remove oxygen and
5 lbs of molecular sieve to remove moisture. Depending on the
application and use, the Gas Purifier may operate for 1-3 months
before initiating the required 13 hour regeneration process to
restore the catalysts.
2.)
Ability to reduce oxygen to 1 ppm in less than 2 hours starting
from 1000 ppm. See Appendix D.
3.)
Ability to reduce moisture below 15 ppm in 2 hours starting from
1000 ppm. The Gas Purifier can further reduce moisture below 10
ppm in 6 hours, below 5 ppm in 16 hours, below 2-3 ppm in 2
days, and as low as 1 ppm in 3-6 days. See Appendix D.
4.)
Internal stainless steel tubing has low permeation rates below 0.10
ppm/min for both oxygen and moisture.
5.)
The sealed blower and circulation system assures leak tight
operation for optimized performance.
6.)
The Gas Purifier has been tested on all three Labconco glove box liner
materials: stainless steel, fiberglass (FRP), and polyethylene. All three
liners meet ISO 10648-2 test methods for oxygen permeation rates
below 1.67 ppm/min when tested at -4 inches of water gauge. The
lowest attainable oxygen levels are 0.2 ppm for stainless steel, 0.4 ppm
for FRP, and 3.5 ppm for polyethylene. The lowest attainable moisture
